A NEW SPECIES OF PARAPHELINUS. 51 



tibia with the superior apical angle narrowed, chitinised, the apical comb hardly 

 developed, with 2-3 spines. Mid legs : tibiae long, spur long and thin. Hind 

 legs : coxae elongate, flat, oval ; tibiae elongate, exceeding those of mid legs, spur 

 short and not half the first tarsal joint. Tarsal proportions : in the fore legs the 

 first and second tarsal joints are subequal (9:8), whilst in the mid and hind legs 

 the first joint is much longer than the second (4:3); joints 3 and 5 are subequal 

 in all the tarsi, 4 being a little shorter. 



Abdomen elongate, acuminate, seen from above at least twice as long as broad, 

 from the petiole to the base of the ovipositor sheath. Dorsal surface smooth, 

 broadly in the middle, except for a narrow scaly reticulate band across the middle 

 of the first tergite. Towards the side this band becomes normally reticulate, while 

 at the extreme sides and on the overlaps of all the tergites the cells are drawn out 

 antero-posteriorly. Posterior tergal edges straight, on 5 and 6 a little convex 

 posteriorly. Tergites 1-5 equal, 6-7 longer. (The first tergite being anteriorly 

 concave appears shorter, but at the sides it is even longer than its successors.) 

 Sternites 1 and 5 are subequal and long, 2-4 much shorter and subequal.

The bristles on tergites 1-3 are wide apart, one at the edge closely accompanied 

 by the second. On tergite 5 the eight bristles form a continuous row with one in 

 front and sometimes one behind at the sides. There are a few (3-5) minute post- 

 spiracular bristles besides the longer transverse ones on tergite 6. The setigerous 

 process on tergite 7 bears four bristles, one shorter. This tergite extends narrowly 

 backwards above the base of the ovipositor sheath, but the bristles borne here are 

 probably of specific value. On the fifth sternite the bristles are arranged 1, 2 and 

 3 on each side of the mid-line. The free portion of the sheath is rather long, and 

 projects distinctly with the ovipositor. 



Male similar to female. The antennal formula the same, with the scape flattened 

 more or less. Wings shorter and broader. Fore legs a little stouter ; second tarsal 

 joint relatively shorter than in the female.
